The present invention relates to moving of lids and has for its object to provide a simple, inexpensive, easily operated, quick, and efiicient mechanical means for moving lids.

Lids, especially the heavier ones, as for instance on the charging spouts of coking ovens, require considerable power to lift the same. In some instances, the lids are sealed by means of a sealing element such as cement which must be broken or released in some way before the lids can be moved. In some instances in such oven lids there are sealing seats between the spout and the lid which become gummed or otherwise caused to stick quite tightly and require considerable power to release the lid from the spout. The present invention aims to provide a device which automatically takes hold of the lid, breaks the seal, removes the lid, and moves it away from the opening of the spout and puts it back into place again in less time than in the prior art; all attained by one mechanism which may be power or manually driven since the mechanism thereof is such that a small initial torque is increased in the device to exert a heavier torque on the lid and a lid is moved and replaced easily and quickly which is important in devices wherein an opening thereof results in loss of substance therefrom.

The present invention is illustrated in the accompanying drawings which form part of this specification and in which: 7

Fig. 1 is a top plan view of a part of a car having the present lid moving device mounted thereon; three such lid moving devices being shown as related to each other and adapted for simultaneously moving the three lids of the charging spouts of a three spout coking oven.

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1 showing the vertical structure and lateral arrangement of the parts more clearly.

Fig. 3 is a vertical section, on a larger scale, taken on line 3-3 of Fig. 2 showing the principle of operation more clearly.

Fig. 4 is a transverse section taken on line M4 of Fig. 3.

Similar reference characters refer to similar parts throughout the views.

Referring now specifically to the device shown in the accompanying drawings:

Th structure A is a portion of an end of a charging car and has the floor It supported on channel members H which form a part of the chassis of the car.

The shaft 52, driven at suitable low rotative r speed by the motor B through the speed reducing element C mounted on channel members of the chassis, is journaled in the bearings l3, l4, and I5 which are mounted on the respective uprights It supported on channel members of the chassis.

The speed reducing element C is of commercial type, is not shown sectionally and is not described herein as to its structure since that is immaterial to the present invention which requires only rotation of the shaft and the means for rotating the same.

The three eccentric mechanisms DI, D2, and D3 are mounted on the chassis; the lateral spacing of the vertical axis of the eccentric mechanisms being arranged so that the same are spaced the same lateral distance as are the axes of the spouts relative to which the lid is to be moved.

Each of the duplicate eccentric mechanisms has the eccentric l'l keyed onto the shaft I2 to rotate therewith. The eccentric strap I8 is disposed over the eccentric and has the boss I9 thereon into which the connector 28 is threaded for longitudinal adjustment thereof and the locking nut 28 is threaded onto this threaded part of the connector and abuts the end of the boss I9 to lock the connector in adjusted position.

The guide members 22, 23, 24, and 25 are supported on the channel members 25 and 21 of the chassis and the filler plates 28 are introduced between the guide. members and the channel members to bring the guide members to proper lateral spacing relative to each other.

The rollers 29 and 3B are journaled on the respective ends of the pivot pin 3i which extends through the hub of the below described arm E and is held against longitudinal movement relative thereto by the pin 32 extending through the hub and through the pin 3 i.

The above mentioned arm E has the above mentioned hub 33 from one side of which extend two spaced ears 34 and 35. The head 36 of the connector 253 is located between the ears and has the pin 37 mounted therein so that the ends of the pin project outside of the head. The rollers 38 and 39 are journaled on the respective ends of the pin 3'! and are held thereon by the screws 40 and the washers M. The two spaced ears 52 and 43 extend from another side of the hub 33.

The part 44 of the arm has the flat tongue 45 extending into the space between the ears 42 and 43; the lateral adjusting shims 46 are disposed between the inside walls of the ears and the outside Walls of the part and the bolts 41 extend hook 48 laterally when required so that the same will line up with and enter the eye 49 on the lid 50 when the device is operated.

The hook 48 is on one end of the stem 5! which latter has the other end threaded into the part 44 for longitudinal adjustment of the stem as a further aid in lining up the hook 48 to enter the eye 49 when necessary. The lock nut 52 threaded into the other end of the stem abuts the outer end of the part 44 and locks the stem in adjusted relation to the part E when the nut 52 is tightened against the end of the part 44.

In the illustration shown, the axes of the eccentric mechanism coincide with the'ax-es of the corresponding. charging spouts 53 of the ovens, herein shown at one side of the driving shaft l3, and consequently with the axes of the respective eyes-49.

The principle of operation of the device is best seen in Fig. 3. The straight line 54 passes through the center of the eye 49, the axis of the guide and the axis of the shaft l l. The line 55 passes through the axis of the rollers 38 and the axis of the shaft [2 when the arm E is in the position shown in Fig. 3.

As the shaft I2 rotates, the eccentric straps I move and pivot the ears 34 and about the pivot pin 3l while the latterremains stationary. The pivoting ofthe ears 34 and 35 causes the arm E to pivot on the pivot pin 3i and this pivoting 7 moves the hook 38 from the position thereof shown in full lines in Fig. 3 to the position shown therein in dotted lines and in engagement with the eye 49 on the lid 58.' When the ears 34 and 35 have been pivoted a certain degree, the rollers 38 abut onthe outside 53 of the guide members 24 and. Hand thereby stop further pivoting of the arm; the hook 48 is pivoted into engagement with the eye 49 as seen in dotted lines in Fig. 3. Further rotation of the shaft I2 and the abutment of the rollers 38 on the outside of the guide member moves the pivot pin 3| and the arm thereon upwardly on the line 54; the rollers 38 and'39 being guided on the sides 56 of the guide and the rollers 29 and 38 being guided in. the guideway between the guide plates 24 and 25;

this upward movement of the 'arm moves the lid 50 away from the charging spout.

Further rotation of the shaft I2 reverses the operation just described and replaces the lid on the oven charging spout.

.The device shown and described is simple of structure, easy and convenient in operation and is efiicient in that all friction producing elements are eliminated therein so that the device can easily be operated by manual power in place of the motor shown. The gravity of the arm E and mechanism and lid thereon can be made use of for the downward movement of the arm and lid become automatic. The eccentric isin uppermost position when the lid issuspended on the arm and the angular relations between elements establishes a dead center. condition and holds the lid in the position away from the oven spout even while the charging car is being moved relative to the ovens.

Having described the present invention and I guide means.

being aware that changes and modifications can be made in the structure and arrangement of parts within the scope and intent of the present invention and the appended claims,
